摘要：
We discuss the cosmic ray spectra in annihilating/decaying Nambu-Goldstone dark matter models. The recent observed positron/electron excesses at PAMELA and Fermi experiments are well fitted by the dark matter with a mass of 3 TeV for the annihilating model, while with a mass of 6 TeV for the decaying model. We also show that the Nambu- Goldstone dark matter models predict a distinctive gamma-ray spectrum in a certain parameter space.
